Magento自定义模块:多个adminhtml格式的图片上传器 [英] Magento Custom Module: multiple Image Uploader in adminhtml form

问题描述

我已经创建了adminhtml模块，它运行正常.在创建新商品的表单中，有4个字段名称，图片，网址和电子邮件ID；

i have created adminhtml module it is working fine. in create new item form there are 4 field name , images, url and email id;

我已经使用文件上传器上传了图片.它工作正常，但我无法上传多张图片.

i have used file uploader to upload images . it is working fine but i am not able to upload multiple images.

是否可以有多个图像上传器?这是我简单的图片上传程序代码.

is it possible to have multiple image uploader? here is my simple image uploader code.

  if(isset($data['image']) && $data['image'] != ''){
        $finderLink = Mage::getBaseUrl(Mage_Core_Model_Store::URL_TYPE_MEDIA) .'finder/store_locator/'.$data['image'];
        $finderName = $data['image'];
        $fieldset->addField('imagelabel', 'label', array(
            'label' => Mage::helper('finder')->__('Location Image'),
            'name'  =>'image',
            'value'     => $finderLink,
            'after_element_html' => '<img src="'.$finderLink .'" alt=" '. $finderName .'" height="120" width="120" />',
        ));

        $fieldset->addField('image', 'image', array(
            'label' => Mage::helper('finder')->__('Change image'),
            'required' => false,
            'name' => 'image',
        ));

    }else{
        $fieldset->addField('image', 'image', array(
            'label' => Mage::helper('finder')->__('image'),
            'required' => false,
            'name' => 'image',
        ));
    }

我需要帮助才能在自定义模块中拥有多个图像上传器.

I need help to have multiple image uploader in my custom module.

推荐答案

您需要为image字段创建自定义渲染器.为此，请在您的模块中创建此类:

You need to create your custom renderer for the image field. For this create this class in your module:

<?php 
class [Namespace]_[Module]_Block_Adminhtml_[Entity]_Helper_Image extends Varien_Data_Form_Element_Image{
    //make your renderer allow "multiple" attribute
    public function getHtmlAttributes(){
        return array_merge(parent::getHtmlAttributes(), array('multiple'));
    }
}

现在在_prepareForm(添加字段的位置)顶部，在添加任何字段之前添加以下行:

Now at the top of your _prepareForm (where you add your fields) add this line before adding any field:

$fieldset->addType('image', '[Namespace]_[Module]_Block_Adminhtml_[Entity]_Helper_Image');

或者，如果您想在政治上正确"，可以通过以下方式添加它:

Or if you want to be "politically correct" add it this way:

$fieldset->addType('image', Mage::getConfig()->getBlockClassName('[module]/adminhtml_[entity]_helper_image'));

这将告诉Magento，在您当前的字段集中，所有类型为image的字段都应由您自己的类呈现.

This will tell Magento that in your current fieldset, all the fields with type image should be rendered by your own class.

现在，您可以像添加字段一样添加字段:

Now you can add your field like similar to how you did it:

$fieldset->addField('image', 'image', array(
            'name'      => 'image[]', //declare this as array. Otherwise only one image will be uploaded
            'multiple'  => 'multiple', //declare input as 'multiple'
            'label'     => Mage::helper('helper_alias')->__('Image'),
            'title'     => Mage::helper('helper_alias')->__('Image'),
            'required'  => true,
        ));

就是这样.
不要忘记用您的值替换占位符([Module]和其他).

That's it.
Don't forget to replace the placeholders ([Module] and others) with your values.

基本上，这是重写/添加所需任何输入类型的方法.创建您自己的类，该类应扩展原始输入类(如果添加新输入类，则扩展为Varien_Data_Form_Element_Abstract)，并在_prepareForm

This is basically the way to override/add any input type you want. Create your own class that should extend the original input class (or Varien_Data_Form_Element_Abstract if you add a new one) and declare it at the top of _prepareForm
